Combined Heat and Power Storage

Technology information

Brayton Battery’s electro-thermal energy storage technology is a fully mechanical solution that stores heat and electricity and provides shippable heat and electricity. It can recover and store (high temperature) heat from an industrial process, excess renewable generation or available cheap electricity from the grid. During peak times in grid demand, the system generates electricity, so that customers do not have to pay a premium for peak-priced grid power. In addition, the KuneVerda/Kaaj ES-CHP can supply stored useful heat to industrial processes. The mechanical ES-CHP solution is reliable, has a long service life (resulting in low energy costs), is scalable and can be used in all climates.
